A lot of people sometimes confuse espresso with “expresso”. Espresso comes from an Italian word that actually means “a cup of coffee brewed expressly”. It is a coffee produced in a machine especially designed for the sole purpose which is to express the coffee. The coffee is placed into that machine with water being forced directly to the coffee at a very high pressure to be able to draw out the whole flavor of the coffee as much as possible.
Creating an espresso is a mixture of art, culture and science. It is art if you understand the tone of the coffee, the machines such as the grinder and the espresso maker. A culture when the knowledge of coffee is learned and practiced then handed down to baristas or to the consumers. The science section is doing the required know-how’s in grinding, maintaining the appropriate temperature and pressure and tracking the right time in the preparation.
So before making your espresso some concerns has to be done towards the coffee beans and the presence of an espresso machine. Choose the coffee beans which are for espresso or you can just buy the beans and have it grind just before having it brewed. Baer in mind that grinding it must be very fine but not to the extent that it is powdery or else there could be chance for an over extraction to occur during the process. Next is the machine, try to consider the machine’s quality as its functionality could always be a factor on how well the espresso is made. Let’s begin and have a good place to start with. Keep in mind the golden rule that a double shot of espresso should be equal to around in between 2 and 2.5 ounces, and should take around 20 t0 25 seconds to extract.
It’s good to have this guideline at heart so that later on you can start testing different espresso variations. Let’s have it done with the brewing temperature, the temperature is basically controlled by the thermostat on your machine and it would be set to around 19 to 195 degrees, the perfect temperature for coffee brewing of any type of coffee. Now let’s go to the brewing temperature, this is the appropriate amount of pressure developed when extracting the coffee and nearly 8 to 9 bars of atmospheres as being the perfect environment set.
Be knowledgeable that great pressure doesn’t actually implies a better tasting coffee. Moving on, we have the pressure of compression, this is the amount of pressure that you exert to compress the coffee grounds that you have placed in the filter handle. The primary technique for compressing is to apply 30 pounds of equally exerted pressure finishing with a twist to polish the top of the exposed coffee grounds.
We have now the key ingredient to your espresso –beans. Select the best beans you have and grind it as close to the time you are to brew your coffee. Coffee making professionals knew that brewing espresso for a long time so with its tricks, methods and tips. As some would say, brewing espresso is simple; it’s the art of making it perfect that would take years and years to be mastered.
